BOX-MAKING MACHINE;

, useful Box-Making Machine, of i which the following is a specification,

The device forming the subject matter of this application, is a machine for binding together,'with spaced bands, the sideform- .ing members of a box, or other receptacle,

the finished material. coming from the machine in the form of a flat blank, which lat-ter is disposed in tubular form, to form the sides of a box, the staves of a barrel or the like.

Presupposing, without prejudice, that the machine is to be employed for the fashioning of. a box, the side-forming blanks or shooks are fed by hand orotherwise, into one end of the machine. Mechanism is provided for feeding the shocks through the machine, and as they are fed through the machine, their ends are trimmed off, so that they are all of equal length. During the progress of the shocks through the machine, they are grooved in their lower faces, transversely, and adjacent their ends, to re ive the ends of the finished box. While the shocks are passing throughthe machine, spaced bands are applied to the upper faces of the shocks, adjacent the ends thereof. Tongues are struck from these bands, the tongues are pressed through the shocks, and clenched upon the shocks.

The invention aims to provide mechanism for holding the. bands which are to be applied to the shocks, mechanism for striking tongues from the shooks, means for embedding the tongues in the shocks, and for clenching them upon the shocks, and structures adapted toguide the bands and theshooks throu h the machine.

WVith the oregoing and other objects in View which will appear as the description roceeds, the inventlon resides in the comiiination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodlment of invention herein disclosed can v be madewithin the 'scope'of what is claimed without de ar-ting from the spirit of the invention.

Fig. 8 is a perspective of the completed box.

In the following description, that end of the structure to which the reference character A is applied, will be considered the forward end of the machine, that end of the structure to which the reference character B is applied, being considered as'the rear end of t e machine.

In carryingout the invention there is provided a supporting structure, including a shooks being denoted by the numeral 5,.

The shocks 5 are fed into the machine, upon the guides 4, adjacent the forward end of the machine, mechanism being rovided for advancing the shocks along t 1e guides a, from the forward end of the machine toward the rear end thereof;

Carried by the guide members l, or secured rigidly, in any other desired manner to the supporting structure, are spaced, upright standards 6, located relatively near to the forward end of the machine. Journaled for rotation in.the standards (5, and

extended t-ransversel of the machine, is a shaft 7 carrying at one end, and beyond one of the standards 6, pulleys 8 and 9, one of which is loose, and the other of which is fixed The pulleys 8 and 9 are to be con-' sidered as typical of any suitable means for,

rotating'the shaft 7. The shaft 7 carries also, afpulley .10, aboutwhich is trained a.

belt 11, passed about a pulley 12, secured t one end of a shaft 14, 'jo irnaled for rotation in bearings 15,'carr1cd by the. lower ends of depending, frame-supported hang ers 16. Secured to the shaft 14, adjacent the longitudinal center of the base 1, is a pulley 17, about which is trained a belt 18,

passed about a superposed pulley 19, carried by a transverse shaft 20, journaled for rotation in bearings 21, preferably secured to the guide members 1. Secured to the shaft 20, adjacent the side members 3, and operating through slots in the guides st, are circular trimming saws 22. shaft 20 is a pulley 23, about which is trained a belt 24, passed about a pulley 25,

carried by a shaft 26, disposed transversely of the machine and supported for rotation similarly to the shaft. 20. Secured to the pulley 17 and the belt 18, causing a rotation of the shaft 20, and a consequent rotation of the trimming sews 22. The shaft '20, through the cooperation of the pulley 23, the belt 24, and the pulley 25, will cause a rotation of the shaft 26, the shaft 26 carrying with it, in its rotation, the grooving saws 27.

From the foregoing, it will be seen that if the box shooks 5 are placed upon the guides at, adjacentthe forward end of the machine, and fed through the machine toward the rear end of the machine, the saws 27 will groove the lower faces of the shooks 5, transversely, and adjacent the ends of the shooks. \Vhen the shooks 5 encounter the trimming saws 22, the ends of the shocks will be cut off, the shooks emerging from the machine, in uniform lengths.

The mechanism whereby the shooks 5 are fed into the machine will now he described. The shaft 7 carries, adjacent one end, a pinion 28, meshing into a larger pinion 21), operativcly connected by means of clutch mechanism 30 of any desired construction,

with a shaft 31, ournalod for rotation in Secured to the the standards (3, above and in front of the shaft 7. Journaled as shown at 32 (see Fig. f 1) upon the pinion 2t), is an inwardly projecting roller 33 (see Fig. 3), the roller 33 being adapted to bear against the edge of an upright lever 34-, fulerumed inlernualiate its ends at 35 (see Fig. l) upon one of the standards 6. To the lower end of the lever 31- is pivoted a forwardly extended link so,

39, secured to the supporting structure, adjacent the forward end of the machine. Secured to the shaft 38, and located between the standards 39, are toothed, friction wheels 40, adapted to engage the shooks 5, to feed the same into the machine. The shaft 38 carries, adjacent one end, a ratchet wheel 41, adapted to be engaged by a pawl 42 (see Fig. 1), the pawl 42 being pivoted upon the arm 37. 7 5

The operation of the feeding mechanism, as hereinbefore described, is as follows: \Vhen the shaft -7 is rotated, the intermeshing pinions 28 and 29 will cause a rotation ofthe shaft 31, the roller 33 upon the pinion 29 engaging the lever 34 and tilting the sanze. When the lever 34 is tilted, the link 36 will tilt the arm 37, the pawl 42 engaging the ratchet wheel 41, and causing a rotation of the shaft 38, whereby the toothed friction wheels 40 will be rotated, urging the shooks 5 into the machine. For a purpose to be described hereinafter, it is necessary that an intermittent rotation be imparted to the frictionwheels 40, and it will be seen that the'engagement between the lever 3-1 and the pinion 29- is such that this intermittent. rotation of the friction wheels 40 will be secured.

Means are provided whereby the box shooks 5 are held down upon the guides 4, for engagement with the trimming saws 22 and with the 'roovin saws 27. To effect these ends, spring fingers 13, one of which appears in Fig. 4, are secured adjacent their forward ends to the standards 6, the rear ends of the fingers 4-3 holding the shooks 5 down upon the guides, above the grooving saws 27. Journaled for rotation in rearward extensions 4-1 of guides. 45 (having functions to be described hereinafter), is a transverse shaft 46, having rearwardly extended spring fingers 47, adapted to press the shocks 5 douuiwardly upon the guides 4,

in the vicinity of the trin'nning-saws 22. In order to adjust the tension with which the fingers -17 bear upon the shooks 5, an arm =18 is secured to the shaft 46, adjacent one end thereof. In this arin'48 there are a series of openings, in which may be nlountcd sm-eessiw-ly, a. pin 50, which, entering suitable openings in the supporting structure, serve to hold the shaft Hi against rotal'ion.

.\lo -.hanis|n is provided. for holding the hands wherewith the box shooks 5 are connected, and for guiding these bands through the machine. This mechanism includes a pair of rotatable reels 52, journaled as at 51, upon the standards 11!), adjacent the upper 126 ends of the standards. The reels are prothe forward end of which is pivoted to a. dopending arm 37, loose upon a shaft 38, disposed transversely of the machine and pref- Cl'tLlJlYJUlltlltllCd for rotation in standards vided with outstanding, grooveddreads 53, upon which are wound bands 54, which ultimately unite the box shocks 5. Fixed to and rising from the supporting structure, adja- 130 standards 55 (see particularly Fig. upon which are journaled as at 56, grooved wheels extended guide arms 58. Springs 59, ex-

57, located in common vertical planeswith the treads 53 of the reels 52. Spanning the wheels 57, and pivoted upon the journaling elements 56 of the wheels 57, are rearwardly tended longitudinally" of the guide arms 58,

are secured at their rearends, as shown at 60, to the guide arms, the forward ends and the springs 59 hearing against the treads of the wheels 57. The tension of the springs 59 is adjusted by means of nut and bolt connections 61 between the intermediate portions of the springs 59 and the guide arms 58. The guide arms 58 are preferably channel members, carrying upon their depending flanges, inwardly projecting plates 62. The bands 54 are extended along the treads of the wheels57, and through the guide arms 58, and the springs 59 act as friction brakes,

bearing against the bands 54, to limit the movement of these bands from the forward end of the machine toward the rear end thereof. In the guide arms 58 there are openings 63, having functions which will be described hereinafter.

A mechanism is provided for punching tongues from the bands 54. This punching mechanism preferably includes dies 64, carried by a. frame-supported, transverse bar 65. 'The dies 64 areadapted to receive punches 66, carried by vertically reciprocating plungers 67, slidably connected, in any desired manner, as indicated at 68, with the standards 6. Pivoted to the upper ends of the plungers 67, are pitmen 69, connected with straps 70, embracing eccentrics 71, secured to the shaft 31.

At this point it may be explained that when the shooks 5 are urged through the machine by the friction wheels 40, the shocks 5 will carry with them, adjacent their ends, the bands 54, the bands 54 moving longitudinally along the lower faces of the guide arms 58, under the wheels 57, against which they are thrust by the springs 59, the bands 54 being reeled oil' the rotatable members 52.

When the shaft '31 is rotated, the pitmen .tion wheels 40, as hereinbefore described.

In order to lift the tongues which are formed in the bands 54, out of the dies 64,

springs 77 are united with the guide arms 58, and with the standards 6. These retractile sprin s 77 serve to elevate the free, rear ends of t ie guide arms58, thereby raising the tongues'which are formed upon the.

bands 54, out of the dies 64, and permitting each band to be advanced farther, so that another tongue may be punched therefrom.

A mechanism is provided for embedding the tongues 89 of the bands in the box shooks 5. This mechanism may be of any desired construction. it consists of presser bars 72, fulcrumedas shown at 73, upon the standards 6 the presser bars 72 carrying hammer heads 74, adapted to engage the bands 54, and to embed the tongues of the bands, initially, in the shocks 5. As denoted by the numeral 75, and as seen in Fig. 3, the forward ends of the presser bars 72 are engaged loosely with the plungers 67, so that when the lungers 67 descend, the forward ends 0 the presser bars 72 will be depressed, thrusting the hammer heads 74 against the bands 54, and embedding the tonguesthereof in the box shooks 5. The elevation of the free, forward ends of the presser bars 72, is effected by means of retractile springs 76, the lower ends of which are connected with the presser bars, the upper ends of the springs being connected with the standards 6. I

A mechanism is provided for embedding the tongues 89finally in the box shooks 5, and for clenching the lower ends of the tongues, against the box shooks. This mechanism embraces a transverse shaft 7 8, jour- 82 are slidably mounted. in the guides 45,

these bearing blocks carrying for rotation, a shaft 83, carrying presser wheels 84, alined with the clencher wheels 80, and coti'perating therewith. The wheels 84 and are maintained in coiiperation, through the medium of springs 85, located within the guides 45, and bearing against the blocks 82, the tension of the springs 85 being adjusted by meansof screws 86 threaded into the upper portions of the guides 45. The bands 54 will be engagedby the presser wheels 84, and be thrust downwardly upon the shooks 5, the tongues which are upon the bands being thrust throu h the shooks, whereupon the clencher wheels 80, will engage the protruding ends of the tongues, and bend the same over upon the shooks 5.

A com leted box, the sides of which are 'connecte by the machine hereinbefore described, appears in Fig. 8.

Preferably however,

formed by the act shooks carry with them the bands shooks 5.

mounted upon the supporting strnctl the shocks 5, into which grooves, the end walls 87 "of the box are thrust. Noting Fig. 7, the bands 54; are shown as provided with the finished tongues 89 which are ion of the punch 66. These tongues 85) are preferably concaved slightly, as shown.

The operation of the device has been dealt with step by step, in connection with the several constituent mechanisms of the machine. A brief resumeof the operation of the structure may, with profit, .however,

be given at this po nt. In practical operahen, the box shocks 5 are placed upon the 15 guides 4, adjacent the forward end of the machine, the shooks being spaced apart, as maybe necessary to permit the ultimate folding of the blank into the form shown in Fig. 8. The friction wheels 40 will urge the 5 forwardly, the grooves 88 being formed by the grooving saws 27, and the ends of the shoolrs 5 being trinnned off by the trimming saws Theshocks 5. when advanced, as hereinbefore described, w'll M, the punches 66 striking the ttmgues 89 from the bands 54, the bands 5st ultimately coming into contact With the SllOOh'S 5, and the hammers 74 setting the tongues 89 initially, into the pass between the presser wheels S-il and the clencher wheels 80, wl'tereupon the tongues 5 the band against the whee 89 will be thrust. entirely through the shooks 5, and be clenched over, as heremlnil'ore set 35 forth.
